If you're looking for a fascinating experience, the Atomium is visually impressive inside and out. Being the most popular tourist attraction of Europe’s Capital and a great picture spot, this iconic landmark was built in 1958 for the Brussels World's Fair and today offers you a surrealistic walk through tubes and spheres. The nine spheres represent an iron crystal magnified 165 billion times, each sphere being about the size of a large apartment. Of course, you have to take the elevator to the top because there you'll find a restaurant with the most beautiful panorama over Brussels and its surroundings. Be sure not to miss the permanent exhibition about the history of the building and the temporary exhibitions, along with the boutique full of original gifts!
